Need help period 5 days early or implantation bleeding?

Stephanie
So this morning when i woke up i had the worst wake up call ever. My period is supposed to come on the 24-25 of every month. This morning however i woke up at 7 to discoverer that i was covered in what i think is my period even though i dont understand because its not time for it and looked like the bed took place in a freddy movie. Sorry a little tmi but cant think of a way to describe it. I haven't had many cramps or felt like i do during my period and ive took pregnancy test this week and have been BFN. Then this morning happened now its already lightning up. Im just confused with my body right now. Ive heard some women have implantation bleeding that has happened like this but dont want to get too excited.
